to get the first term to be 6x you need to mulitply by 3 but if you did then the equation would be 6x + 6 = 30 so it is not equivlent
6x + 6 = 30
if you multiply both side by 3 you get 6x + 6 = 30
2x+8
if you subtract 2 from both sides you get 2x = 8
6x = 10
to get the first term to be 6x you need to mulitply by 3 but if you did then the equation would be 6x + 6 = 30 then if you subtract 6 from both sides you get 6x = 24 so it is not equivlent
